This paper presents the development of active noise control (ANC) for earphones, which uses natural sound for estimating the secondary path model instead of extra random noise. Real-time experiments are conducted to evaluate the performance of the developed ANC earphones using the microphone inside KEMAR's ear. Experimental results show the developed light-weight ANC earphones achieve higher noise...
This paper analyzes the performance of off-line secondary path modeling algorithms for narrowband active noise control (ANC) systems. The accuracy and convergence rate of adaptive system identification will be degraded by disturbance. A delayless filterbank is utilized to partition the full-band excitation and error signals in order to reduce the order of the secondary-path model and increase the...
